“People react positively when things are clear and understandable.”
The best applications
react
to the user's workflow
not
the other way around

Know
Know your solution's target audience
Usability
Make your audience want to use your solution
Reliability
Make your solution fault tolerant
Simplicity
Make your solution intuitive, for both consumers and developers
start with the
Visuals
of your solution
Why?
“As far as the customer is concerned, the interface is the product.”

Use
SWT
&
OSGi
for modular purpose built solutions
How?
“Before software can be reusable it first has to be usable.”
Modular Components
Create reusable SWT widgets
Tailors the look and feel to the purpose of the solution
Employ OSGi services when possible
Allows for specific assemblies and rapid development
Native widgets provide a natural look and feel
Provides the ability to build a professional looking solution quickly
Integrates with JFace for easy MVC development
Limiting for low-light workflows in imaging
Provide analagous widget set that is skinnable
Allows the solution to be tailored to any visual requirements
Focus on the low light workflow

Inject different implementations at runtime
Use same services and interfaces on both clients and servers
Different assemblies just contain different service implementations based on the use case

What?
“The behavior you’re seeing is the behavior you’ve designed for (whether intentional or not).”
Rethink

What the user can do
How it responds
How the solution is delivered

Great Solution
Now What?
Diagnostic Imaging requires heavy duty hardware
($10,000+ Monitors, and multiple at that!)
Clinicians, Nurses, Surgeons, etc. want the same tools and capabilities
(Without the access to the hardware)
(and they don't want to install anything)
Need a way to
Deliver
The same solution to the enterprise
Citrix?
VM Ware?
Require plugins
Network intensive for imaging
(Up to 3MB per second!)
Use the modules we already have
Build on what the other guys do
(Remote Desktop Services)

So what does it
Look
Like?
Now we can run on
Anything
with a browser!
What's Next?
Third Parties can
Contribute
Modules for specialized functionality
(we've got an SDK!)
So what do
